Patent SE-301999-B (SE)
Inventor: ULMER W
IPC: H03G1/00
Filed: 1962-06-29
Abstract: 944,682. Semi-conductor circuits; automatic gain control. SIEMENS & HALSKE A.G. June 26, 1962 [June 30, 1961], No. 24448/62. Headings H3R and H4T. In a multi-stage transistor amplifier having variable attenuators controlled in accordance with signal level connected between individual stages the control is such that the attenuation of the attenuator last in the direction of transmission is first increased to its maximum before the attenuation of the preceding attenuator is increased. Fig. 3 shows a wide band transistor amplifier with variable attenuators I, II and III each comprising a network of diodes D1, D2 and the emitter-base junction of the following transistor amplifier, the gain control signal being applied to the terminals - UR, + UR and Ue, to control the current through the diodes and therefore their impedances, the preferred arrangement being that the shunt diode D1 is operated with zero current through it while current is flowing in the series diode D2 and vice versa. Resistors R4, R5 and R6 are provided to limit the range of the attenuator and the variable capacitor is provided in series with D1 to adjust the frequency response. Since the frequency response of the attenuators may be compensated to be similar at maximum and minimum attenuation but will depart from this response in intermediate attenuation conditions, the arrangement according to the invention enables the frequency response to be maintained within close limits since only one attenuator is at other than its maximum or minimum attenuation at any one time. If slow response to changes in level is required the diodes may be replaced by thermistors.

Title: Working depth control system for vehicle with ground working implement
Inventor: WIEGARDT GORDON K
IPC: A01B63/00
Filed: 1983-03-21
Abstract: A tractor (10) includes a hitch (26) for pulling a ground-working implement. A hydraulic cylinder (34) is extensible and retractable to lower and raise the implement. A control syytem (50) senses operating parameters, including wheel slip, engine speed, draft force and implement or rockshaft position. Error signals are derived from the sensed wheel slip, engine speed and draft force and correspond set point signals. The error signals are combined into a composite or combined error signal. The larger of (a) the combined error signal and (b) a separately determined position error signal. is selected and converted to a pulsewidth modulated valve control signal which is applied to a control valve (42) which then actuates the cylinder to move the implement to reduce the magnitude of the selected error signal. Certain set point signals are derived from the corresponding parameter signals themselves.

Title: Process for the production of ethanol
Inventor: MCCORMACK CHRISTOPHER ALPHONSU
IPC: C12P7/10
Filed: 1996-05-22
Abstract: A process for producing ethanol from a vegetable material comprises subjecting the vegetable material to an enzymatic treatment with a mixture of enzymes which is capable of saccharifying the vegetable material and converting the sugars so produced to ethanol. The enzymes used include enzymes capable of degrading cellulose, hemicellulose and starches. The conversion of the sugars produced in the saccharifying step to ethanol is carried out in the presence of a mixture of yeasts selected from the genera Candida, Kluyveromyces, Pischia and Saccharomyces. The entire process is carried out in a single reaction vessel and typically takes less than 3 hours to proceed from the raw material (untreated straw, grain, etc.) to a distilled ethanol product. The yield of ethanol can be increased by adding an enriched glucose solution to the reaction mixture.

Title: Method and apparatus for adjustment of TCP sliding window with information about network conditions
Inventor: RUUTU JUSSI
IPC: H04L12/56
Filed: 1999-07-01
Granted: 2003-08-13
Abstract: A method and apparatus for adjustment of TCP sliding window with information about network conditions is disclosed. The present invention obtains information from the network below TCP about the condition of the network and traffic and uses this information to control the transmission of the TCP source without any modifications to the existing TCP sources. The invention includes the steps of receiving feedback information in an acknowledgment packet, receiving a packet having an advertised window field set to an original advertised window size for a sliding window, and modifying the advertised window field to chose the size of the sliding window in response to feedback information received in the acknowledgment packet. The original advertised window size indicates the original size of a sliding window for determining a number of bytes that can be sent before an acknowledgment packet is received. The feedback information further includes a window advertisement. The size of the sliding window includes the minimum of the window advertisement and a congestion window. The window advertisement specifies an increase to the size of the sliding window. The increase includes an additional number of octets of data a receiver is prepared to accept. The method further includes the steps of calculating a modified advertised window size using the window advertisement, comparing the modified advertised window size to an original advertised window size and transmitting an acknowledgment including the least of the modified advertised window size and the original advertised window size.
